### 10.3.2.5 Detecting and responding to misconfiguration

There MUST be mechanisms for detecting and responding to misconfigurations. If a command is executed incorrectly, the router SHOULD give an error message. The router SHOULD NOT accept a poorly formed command as if it were correct.

DISCUSSION

  There are cases where it is not possible to detect errors: the command is correctly formed, but incorrect with respect to the network. This may be detected by the router, but may not be possible.

Another form of misconfiguration is misconfiguration of the network to which the router is attached. A router MAY detect misconfigurations in the network. The router MAY log these findings to a file, either on the router or a host, so that the network manager will see that there are possible problems on the network.

DISCUSSION

  Examples of such misconfigurations might be another router with the same address as the one in question or a router with the wrong address mask. If a router detects such problems it is probably not the best idea for the router to try to fix the situation. That could cause more harm than good.
